Here's where we separate the dtp wanna-be's from the pros.
Objects closer to the ground plane cast a darker shadow
than those further away. You can test this by simply making
a lighter shadow and offsetting it more from the object.
The object then looks like its coming up higher off the
ground plane.

For objects resting on the ground plane,
shadows get darker as they get closer to the object, and
lighter as they move away. This can
be done with an airbrush tool, paintbrush, or any tool that
darkens or paints. In Photoshop, the burn tool is a perfect
choice in that it darkens and saturates the overall area
without making it look blotchy or flat.
